Continuity mistake: In the scene were Lloyd finds Harry's "treasure chest", you can see that the chest is laying flat against the wall, but when the Principal and the lunch lady come and find it missing, there is a small dirt outline, as if the chest was pointing out from the wall, instead of larger outline, as if it were flat against the wall.
Continuity mistake: When Lloyd is at Harry's window trying to wake up with him, the shards of glass on the windowsill keep changing positions. In the final shot of the scene, they have disappeared altogether.
Continuity mistake: When Jessica is chasing the bus to the museum, her hubcap comes off after she goes airborne over the hill. It is back on in the next shot.
Continuity mistake: When Lloyd is sticking the napkins on himself in the cafeteria, you can see he is wearing underwear under the napkins, while in the next shot he isn't.
Continuity mistake: When Harry and Lloyd first collide, if you look carefully you can see that Lloyd still has his entire tooth when he falls. It was supposed to be chipped.
Continuity mistake: When Ms. Heller is talking to the tour guide at the museum, she offers her a $5 bill to take the tour twice. How the bill is folded and held changes. When Ms. Heller says do the tour twice it's pinched between her fingers, then it's folded in half. It keeps switching between folds. (00:35:19)
Suggested correction: I didn't see it folded at all. The "other half" or part of the $5 bill that you can't see is actually squished/crumbled in the palm of Heller's hand.
The mistake is partially valid, its position changes. You seem to be talking about when she has the $5 and camera in her hand. When she says do the tour twice, it's pinched between her fingers, then in the next shot, it's folded in half, then she's pinching the end and the other end is unfolded, then back to folded in half.
Regarding the "folded in half" - the $5 bill is folded, but VERTICALLY. The differences that are shown appear to be deliberate SLEIGHT OF HAND. Heller is flashing the whole $5 bill at first, then crumbles it (symbolizing it "going away"). By having the $5 folded vertically, Heller was able to quickly fan out the left side (part equivalent to a flat $5 bill), then hold the $5 to resemble a bow tie. Folded vertically, the $5 bill could be manipulated to look different and more or less appealing.
She never crumbles the $5 bill during the part the mistake occurs. The way she's holding the bill changes between shots, meaning no time elapses, so there can be no deliberate sleight of hand.
Or would that be HORIZONTALLY? The $5 bill is folded to be long, not short, if this clarifies what I'm trying to say.
Continuity mistake: When Jessica and the principal are in his car watch the driver's side mirror. When Lloyd and Harry are following them you see a side view of the car and it has a regular teardrop mirror. After Lloyd and Harry get ice cream the principal is telling Jessica no one will be looking for her and the side view mirror has gone to a big square truck mirror like welded to the door.
Continuity mistake: When the bus is driving to the museum the camera goes to Lloyd and Harry. In the window you see a car passing. When the movie shows an overhead shot of the road, there is no car in front or to the side of the bus.
Continuity mistake: In the scene when "There's shit everywhere" in the bathroom, it is taking place at night. But in the shots of Jessica's dad in the bathroom doorway, there is sunlight coming through the window across the hall.
Continuity mistake: When the teacher asks her "special needs class" if they have any ideas for a float, the camera switches between people and conversations and every single time this happens the Chinese exchange student changes position (resting on her elbow, arms out stretched, hands together etc...)
Continuity mistake: Louis has a black eye from Lloyd hitting him while in his pirate costume, as Lloyd finds out when he is wearing the "polar wear". Then, in the special needs class that same day, we see Louis without the black eye.
Continuity mistake: When Harry is drinking his Slushy fast, some drips on his neck and leaves a stain. Then, when Jessica comes, the stain is gone.
Continuity mistake: The chip of Lloyd's tooth on Harry's forehead is bigger than the piece missing.
Continuity mistake: When Harry and Lloyd fall through the ceiling, they start to walk down the hall, away from the ceiling debris, for about 20 seconds, but when the camera angle changes to their backs, they're next to the debris again.
Continuity mistake: When Harry and Lloyd are in Big A goofing off, when Lloyd says "invisibility shield", the store clerk is seen moving and bending over a bit to put something down on the shelf, but in the next shot, he's back in the upright position.
Continuity mistake: When the special needs class is debating a float, look at the chalkboard in the background. The word 'float' is underlined, then the next time you see it, it isn't underlined. This occurs a number of times throughout the scene.
Continuity mistake: After Lloyd breaks the window with his message via a large brick, the glass on the left side of the window sill keeps shifting back and forth 90 degrees from shot to shot.
